Demonstrates how to use the sendbird_chat plugin.
44

5+
## Usage
6+
This example app requires the inclusion of a `.env` file located in the example root directory. Simplest option is to add your Sendbird keys to the `.env_sample` file and rename the file to `.env`.
7+
8+
## Polling
9+
Because there doesn't appear to be a public websocket endpoint, this example app polls sendbird periodically for available users and open group channels and every second when the chat window is open.
